' with clay-end other: material that is to; be broken up for the 'of" brieks-or The main features ofn'evelty to" be herein described and claimed comprises. series" of novel cutters havingax cqnstruction whereby they may he applied tejor removed the cutter-carrying'rellerg-i Herein the cutter iscrosseshaped and-hasfa plurahtyof cutting edges, shown'as four and as an edge becomes: V

groove fironrwhich it was with! drawn.

Ordinarily when a provided with 1-series of cutters each having but one cutting 'jedge whenever anfedge becomes dull the (machinehas to'be stoppe and the cutter has to 30'- be removed and reground, which'necessitates;

part of the-attendants ofthe'niachine; but also"- very materialn oment. j

A I The cutter-carryinggroller v comprising-a shaft O", on which arekeyed two hollow nietallie' sleeves'or hubs-def, said :hubs having, resgeetively, outwardly 1* extended-- flanges cwfl said flanges outside of'said hubs, having made through them severaleutter-rec of cross shape, said'openthe cross-shaped cutters D.- flhehuhs have a series of r shaped passages 0", that receive three of theedges 5 of. the cross-shaped-eutter Dgfifld these T-shaped'passagesare .eontinued to andforn'i part of the cross-sha openings v in the flangea- Each opening is shaped as best hown in Fig. 2, and the end of the outer:

branch ofeach opening is beveled, as-at 2, 1

(see Fig. 4;, to receive againstit thebeveled face .3 of the head of a clamping device d'.,"-sh0wn w as threaded at one end to receive a nut (i by which to draw said device outwardlyrthrough' L the flange, the under side of said fdevice acting harder and harder against the-then outermost face 1 of the cutter D. Y 1 r Each cutter (see Figs. 1, 2, and'fi) has a plu rality of. cuttin'gedges 5. Theleutter shown as cress shaped hasfour' eutting'dgeaeither of which may be used, and these edges may be-exposed for use one after the other, as when one of the four sharpened edges dull the "clamping 'device holding it-in the roller v maybe moved inwardly to release-thecutter,

and thereafter said cutter maybe drawn'out "of the roller-through oneof the cross-shaped ope!iingsinth ,flange and be turned partially around its longitudinal axis and be reins erted" 9 in the, roller with 'a fresh or sharp edge 'exqsee'forxiuse;

roller are keyed'to the speed,'said rollerbedriven at a verymu'ch'higher ingin pr ties than the feed-roller B, on. which the 'otherj e'arthy [hatter beingeut up I disintegrated descends from the hopper and rests. V a

The metallic hubs cc', forming part of the cutter-carry'ing-roller, are made hollow for part of their length to thereby lighten their weight, and the abutting edges of the two hubs are cored to leaveto be ground true only ring-shaped ends.

The bearing B for the shaft B is shown as made adjustable by suitable adjusting devices, (represented as screws B so that the space between said rollers may be regulated according to the stock being handled and the work being done. I

- The periphery of the roller B enters and substantially fills the spaces between the flanges a a of the cutter-carrying roller, The

inner side of these flanges are in alinement, preferably, with the inner side of the hopper,

so that all clay or other earthy matter entering the hopper comes directly onto the rollers .B- and C and goes between the roller and the :roller C.

, By providing the hubs 0 of the shaft C with flanges fixed thereto that project beyond the cutter. clay may be run through the machine betweenthe cutter-carrying roller and feedv "ing-roller. without the clay coming onto the shaft C? and getting between said shaft and the bearings 0*, which is a matter of very considerable importance, as it results in saving of wearof the more expensive parts of the machine." a

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is i a z Witnesses:

1. In a machine of the class described, a feed-roller, and a cutter-carrying roller provided with a series of T-shaped grooves, combined with a series of cross-shaped blades having each a plurality of cutting edges, each edge of which. may be used when desired and means for securing said blades in the grooves. 2. 'In a machine of the class described, a

cutter-carrying roller provided with a series of T-shaped grooves and a series of. crossinto the passages of said flange and through vsaid grooves in the body of the roller, each cutter having a plurality .of cutting edges shaped cutters fitted in said grooves, said cut- I ters having a plurality of cutting edges, and

either of which may be used, the stock passing between said rollers being kept from contact with the shaft carrying said cutter-roller and'from the bearings therefon. 1

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses. v
